Java Excel API

The Java Excel API is a set of classes and interfaces that allow developers to read and write Excel spreadsheets using the Java programming language. The API is part of the Apache POI project, which provides a number of libraries for working with Microsoft Office documents.

The Java Excel API can be used to perform a variety of tasks, including:

* Reading and writing Excel spreadsheets
* Creating and formatting Excel spreadsheets
* Manipulating data in Excel spreadsheets
* Importing and exporting data from Excel spreadsheets

The Java Excel API is a powerful tool that can be used to automate a variety of tasks related to Excel spreadsheets. It is a valuable resource for developers who need to work with Excel spreadsheets in their Java applications.

Here is an example of how to use the Java Excel API to read an Excel spreadsheet:

import org.apache.poi.ss.usermodel.*;
public class ReadExcel {
public static void main(String[] args) {
try {
// Create a workbook object
Workbook workbook = WorkbookFactory.create(new File(“path/to/excel_file.xlsx”));
// Get the first sheet from the workbook
Sheet sheet = workbook.getSheetAt(0);
// Iterate over the rows and cells in the sheet
for (Row row : sheet) {
for (Cell cell : row) {
// Print the cell value
System.out.print(cell.toString() + “\t”);
}
// Print a new line
System.out.println();
}
// Close the workbook
workbook.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
